Description Thomas Deutschmann gentoo-dev Security 2019-11-30 16:40:48 UTC
Incoming details.
Comment 1 Thomas Deutschmann gentoo-dev Security 2019-12-12 16:58:34 UTC
===========
Description
===========

When the libssh SCP client connects to a server, the scp
command, which includes a user-provided path, is executed
on the server-side. In case the library is used in a way
where users can influence the third parameter of
ssh_scp_new(), it would become possible for an attacker to
inject arbitrary commands, leading to a compromise of the
remote target.

==================
Patch Availability
==================

Patches addressing the issues have been posted to:
https://www.libssh.org/security/

Additionally, libssh 0.9.3 and 0.8.8 have been issued as
security releases to correct the defect.
SSH administrators are advised to upgrade to these releases
or apply the patch as soon as possible.
